Making split CD's with likeminded bands is alright. Making split CD's with bands where you can't tell one from the other is a way of saying that they lack originality entirely and copy each other.

And, honestly, as far as black metal goes, what you have here on Tenebrae In Perpetuum and Krohm is really a quite boring listen. It's all the same from end to end; the same mid-tempo deal with no variation whatsoever.

Yawn.

Next, please.
